  1. Question 1

    Q1. A student's hand tremors during exams improve with beta-blockers. What physiological mechanism explains this?

    • A) Reduced sympathetic nervous system activity
    • B) Increased parasympathetic tone
    • C) Neurotransmitter receptor blockade
    • D) Central nervous system depression

    Answer: Reduced sympathetic nervous system activity

    Explanation: Beta-blockers inhibit fight-or-flight responses. Reduced sympathetic nervous system activity is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
